| 13 | The ADIN1110 is a low power single port 10BASE-T1L MAC- |
| 14 | PHY designed for industrial Ethernet applications. It integrates |
| 15 | an Ethernet PHY core with a MAC and all the associated analog |
| 16 | circuitry, input and output clock buffering. |
| 17 | |
| 18 | The ADIN2111 is a low power, low complexity, two-Ethernet ports |
| 19 | switch with integrated 10BASE-T1L PHYs and one serial peripheral |
| 20 | interface (SPI) port. The device is designed for industrial Ethernet |
| 21 | applications using low power constrained nodes and is compliant |
| 22 | with the IEEE 802.3cg-2019 Ethernet standard for long reach |
| 23 | 10 Mbps single pair Ethernet (SPE). |
| 24 | |
| 25 | The device has a 4-wire SPI interface for communication |
| 26 | between the MAC and host processor. |
